'Waist' in the Bible

This is what the LORD told me: "Go and buy a linen belt for yourself, and put it around your waist. But don't let it get wet."

So I bought the belt according to the LORD's instruction, and put it around my waist.

Take the belt that you bought and that is around your waist. Get up and go to the Euphrates, and hide it there in a crevice in the rock."

For just as the belt clings tightly to a person's waist, so I've made all the people of Israel and all the people of Judah cling tightly to me,' declares the LORD. "I did this so that they would be my people, name, praise, and glory. But they wouldn't listen.'
